LAY-MOTION FOR LOOIVIS.

SPECIFICATION forming part of Letters Patent No. 763,088, dated June 21,1904.

Application filed April 4, 1904=. Serial No. 201,372. (No model.)

To (all whom it may concern:

Be it known that I, ARTHUR S. CowAN, a cititer, in the county ofWorcester and State of Massachusetts, have invented certain new anduseful Improvements in Lay- Motions for Looms, of which the following isa specification.

My invention relates to looms, and more particularly to the lay and itsoperating mechanism with a yielding connection.

The object of my invention is to provide an improved yielding connectionintermediate the crank-shaft which operates the lay and the lay-sword,so that when the lay protects to stop the loom the continued movement ofthe crank-shaft, which is not immediately stopped, will move theyielding connection and not force forward and possibly break thelay-sword.

In my improvements I provide a pivoted arm which is pivotally andyieldingly attached and connected to a link or connector intermediatethe crank-shaft and the laysword, hen the lay protects on its forwardmovement, the continued movement of the crank-shaft causes the arm,yieldingly attached, to move, and thus allow the continued movement ofthe crank-shaft on the stopping of the lay-sword, as will be hereinafterdescribed.

Referring to the drawings, Figure 1 isa sectional elevation of aloom-frame and lay with my improvements applied thereto and showing thelay in its rear position; and Fig. 2 corresponds to Fig. 1', but showsthe lay in its protected position.

In the accompanying drawings, 1 is a portion of the loom side or end. 2is the lay-sword, attached at its lower end to the lay-foot 3, mountedon the rock-shaft 1. The lay-sword 2 carries at its upper end the lay 5,having the race-plate 6 thereon. stand 7 is secured to the front loweredge of the lay and carries the rod 8, having the protector-finger 9fast thereon, which is adapted,

when the shuttle is trapped in the shed to en-.

gage the hunter-lever 10 on the hunter-stand The protector-rod 11,secured to the breast-beam 12, on the forward movement of the lay.

All of the above-mentioned parts -may be of the usual and well-knownconstruction and operation.

I will now describe my improvements:

To the rearwardly-extending ear 2 on the lay-sword 2 is attached, by apin 2 or otherwise, one end of a link or connector 13. The other end ofsaid connector 13 is attached, in this instance bya pin 14, orotherwise, to one end of the crank-connector 15. The other end of saidconnector 15 is attached to the crank 16 on the crank-shaft 16 in theusual way.

The link or connector 13 has adownwardlyextending projection 13' at itsinner end, and to the lower end of said projection is pivotallyconnected, in this instance by a pin 17 the upper end of a pivoted arm18. The lower end of the arm 18 has in this instance a recessed portion18 to fit onto the upper side of a stud 19, secured to the loom-frame 1,and side extensions 18, extending out from the recessed portion 18.

Each side extension 18" has a hole therein through which looselyextendsa bolt 20. The headed ends 20 of the two bolts 20 are secured inside extensions 21 on a half-hub piece 21, which extends upon the lowersurface of the stud 19.

A spiral spring 22 encircles each bolt 20 and is confined between a nut23 on the bolt and the upper side of the side extension 18. A secondlock-nut 24 may be used on each bolt 20. v

The springs 22 act to yieldingly hold the side extensions 18" in contactwith the side extensions 21 and yieldinglyhold the recessed portions 18and half-hub portion 21 on the stud 19 to form a complete hub or collarand pivotally and yieldingly secure the lower end of the arm 18 on saidstud, as shown in Fig. 1.

The pivoted arm 18 is not connected directly with the lay-sword, andsaid arm has a support of its own, as the stud 19, on which it has anindependent swinging movement parallel with the movement of thelay-sword, and said arm 18 acts to support one end of the link orconnector 13 and the crank-connector 15.

The operation of my improvements will bereadily understood by thoseskilled in the art.

When the lay moves forward and protects, as shown in Fig. 2, theprotectorfinger 9 strikes the hunter-lever 10, whichmoves back in thehunter-stand 11 in the usual .way.

The movement of the hunter lever 10, through mechanism (not shown) ofordinary construction and operation, ships the belt or throws off thepower to stop the loom; but the crank-shaft 16 does not stopimmediately, but pushes, through the crank-connector 15, the link orconnector 13 in an upward direction, and the arm 18 moves up with it,causing the springs 22 to be compressed and the recessed part 18 to beseparated from the half-hub part 21, as shown in Fig. 2, and thusrelieve the connector 13 and thelay-sword 2 from the strain which mightbreak one or both of them.

It will be understood that the details of construction of myimprovements may be varied, if desired.

Having thus described my invention, what I claim asnew,and'desi-retosecure by Letters J. G. DEWEY, HAAS.
